PalmSHIELD has designed its own line of industrial hinges: The Gorilla Hinge. This hinge uses a half inch thick plate to mount to both the gate and gate post. The Gorilla Hinge has a slight offset on the hinge plates to allow the gate to slightly close past full close. This intended design quirk was incorporated because we realize that not everything happens exactly like you want it to in the field. We empathize with potential field irregularities and believe it is our responsibility to find a solution to offer our customers some flexibility.
